Background Art

[0002] With the development of multi-input multi-output (MIMO), an uplink simultaneous transmission scheme has been proposed to achieve higher uplink (UL) throughput and reliability. In such a scheme, simultaneous UL transmissions from multiple UE panels are scheduled by a single downlink control information (DCI). In addition to parallel UL transmissions across cells, UEs are also permitted to perform UL transmissions simultaneously within the same cell. However, the total transmission power of UL transmissions in the serving cell within the frequency range for each transmission opportunity does not exceed the maximum UE transmission power. Therefore, it is necessary to enhance in terms of power allocation and power reduction.

[0025] In a conventional communication system, in the case of single-cell operation using two UL carriers or in the case of operation using carrier aggregation (CA), the total UE transmission power for UL transmission (e.g., PUSCH, PUCCH, PRACH, or SRS transmission) in the serving cell in the frequency range of each transmission opportunity i

[0026] MIMO is enhanced in terms of simultaneous UL transmissions from multiple panels, and two PUCCHs or two PUSCHs can be transmitted simultaneously within one cell. Therefore, it is necessary to design a transmission power control rule considering the simultaneous UL transmission operation. In addition to the prioritization of power reduction between cells, it may also be necessary to define the prioritization within the cell for simultaneous UL transmissions.

[0027] To solve the above and other potential problems, embodiments of the present disclosure provide a power control method. This method relates to the allocation of transmission power and the prioritization of transmission power reduction for simultaneous UL transmissions in a single serving cell and parallel UL transmissions across multiple serving cells. In particular, power control for simultaneous UL transmissions from multiple panels is achieved by allocating transmission power in the order of the power allocation priorities of each UL transmission. As a result, the performance of the UL transmission operation is improved.

[0028] FIG. 1 shows an exemplary network system 100 in which exemplary embodiments of the present disclosure may be implemented. As shown in FIG. 1, the communication network 100 may include a terminal device 110 and a network device 120. The network device 120 may be associated with, include, or be composed of at least two transmit-receive points (TRPs) (122 and 124). The serving cell 102 is composed of both TRPs (122 and 124), and the serving cell 104 is composed of the TRP 124.

[0029] The network system 100 may be a multi-TRP system. The terminal device 110 may operate on multiple UL carriers or may operate in carrier aggregation (CA). In the case of CA, the serving cell 102 can also be referred to as the primary cell or P cell, and the serving cell 104 can also be referred to as the secondary cell or S cell. In some embodiments, the network device 120 is composed of one or both of the TRPs (122 and 124). Alternatively, in other embodiments, the network device 120 is separate from the TRPs (122 and 124) and manages the TRPs (122 and 124).

[0030] The terminal device 110 supports simultaneous transmissions such as simultaneous PUCCH (Physical Uplink Control Channel) transmission and PUSCH (Physical Uplink Shared Channel) transmission across multiple panels, and the simultaneous transmissions are scheduled by a single DCI. In the context of the present disclosure, the term "simultaneous transmission" refers to at least two PUCCH transmissions or at least two PUSCH transmissions transmitted in the same (serving) cell. The simultaneous UL transmission can be transmitted based on space division multiplexing (SDM), frequency division multiplexing (FDM), or single frequency network (SFN) mode. For the sake of discussion, various modes are briefly described below. In the SDM mode, different layers or DMRS ports of one PUSCH are precoded separately and transmitted simultaneously from different UE panels. In the FDM-A mode, different parts of the frequency domain resources of one PUSCH transmission opportunity are transmitted from different UE panels. In the FDM-B mode, two PUSCH transmission opportunities with the same RV or different RVs of the same transport block (TB) are transmitted from different UE panels on non-overlapping frequency domain resources and the same time domain resources. In the SFN-based transmission mode, all of the same layer or DMRS ports of one PUSCH are transmitted simultaneously from two different UE panels. In the SDM repetition mode, two PUSCH transmission opportunities with different RVs of the same TB are transmitted simultaneously from two different UE panels.

[0031] In the context of this disclosure, terms such as UL beam, spatial relation information, UL transmission configuration indicator (TCI) state, joint or common TCI state, spatial filter, power control information, power control parameter set, UE panel or panel ID, positioning information Type-D (or any other type such as Type-A, B, C, etc.) may be used interchangeably. A UE panel may be identified by an index of a set of UE capability values or a panel ID. Alternatively, or additionally, the panel may be identified or associated by at least one reference signal (RS) or simply by a UL beam.

[0032] It should be understood that the numbers of network devices, TRPs, and terminal devices shown in FIG. 1 are provided for illustrative purposes without suggesting any limitation. The communication network 100 may include any suitable number of network devices and terminal devices.

[0033] Depending on the communication technology, the communication network 100 can be a Code Division Multiple Access (CDMA) network, a Time Division Multiple Access (TDMA) network, a Frequency Division Multiple Access (FDMA) network, an Orthogonal Frequency Division Multiple Access (OFDMA) network, a Single Carrier - Frequency Division Multiple Access (SC - FDMA) network, or any other one. The communication discussed in network 100 can comply with any suitable standard including, but not limited to, New Radio (NR), Long Term Evolution (LTE), LTE - Evolution, LTE - Advanced (LTE - A), Wideband Code Division Multiple Access (WCDMA (registered trademark)), Code Division Multiple Access (CDMA), cdma2000, and Global System for Mobile Communications (GSM), etc. Further, the communication can be executed according to any generation of communication protocol known currently or developed in the future. Examples of communication protocols include, but are not limited to, the communication protocols of the first generation (1G), the second generation (2G), 2.5G, 2.75G, the third generation (3G), the fourth generation (4G), 4.5G, and the fifth generation (5G). The technology described in this specification can be used not only for the above - mentioned wireless networks and wireless technologies but also for other wireless networks and wireless technologies. For clarity, in the following, one aspect of the technique will be described with respect to LTE, and LTE terms will be used in many of the following descriptions.

[0034] The principles and implementations of the present disclosure will be described in detail below with reference to FIGS. 2 - 6. FIG. 2 is a signaling chart showing an exemplary procedure 200 for transmission power control in some exemplary embodiments of the present disclosure. Procedure 200 may include a terminal device 110 and a network device 120 as shown in FIG. 1. For the sake of discussion, procedure 200 will be described with reference to FIG. 1.

[0035] In procedure 200, the terminal device 110 can operate in simultaneous multi-panel UL transmission in either or both of cells 102 and 104. In some exemplary embodiments, the terminal device 110 can attempt a plurality of UL transmissions that at least partially overlap in the time domain. Each of the plurality of UL transmissions may be associated with a respective priority index.

[0036] In some exemplary embodiments, the network device 120 can transmit (205) an indication indicating the priority associated with a first set of simultaneous transmissions on cell 102 via at least one of an RRC message, a MAC CE, or a DCI. The first set of simultaneous transmissions includes at least a first transmission and a second transmission that at least partially overlap in the time domain. In some other embodiments, such a priority associated with the first set of simultaneous transmissions may be predefined or specified for both the terminal device 110 and the network device 120. Thus, step 205 is optional for procedure 200.

[0037] Figures 3 and 4 show examples of UL transmissions for a plurality of serving cells according to some exemplary embodiments of the present disclosure. As shown in Figure 3, the first set of simultaneous UL transmissions includes a first transmission 310 and a second transmission 320 scheduled by a single DCI on cell 102. Cell 102 may be composed of a plurality of resource sets such as an SRS resource set, a CORESET, etc. Further, a third transmission 330 is scheduled by another DCI on cell 104. The first set of simultaneous UL transmissions (310 and 320) and the third transmission 330 at least partially overlap in the time domain.

[0038] As shown in FIG. 4, the first set of simultaneous UL transmissions includes a first transmission 410 and a second transmission 420, which are scheduled by a first DCI on cell 102. Further, the second set of simultaneous UL transmissions includes a fourth transmission 440 and a fifth transmission 450, which are scheduled by a second DCI on cell 104. Cells 102 and 104 may be composed of a plurality of resource sets. The first set of simultaneous UL transmissions (410 and 420) and the second set of simultaneous UL transmissions (440 and 450) at least partially overlap in the time domain.

[0039] Before transmitting a plurality of UL transmissions, the terminal device 110 determines (210) whether the total transmission power of the plurality of UL transmissions exceeds a transmission power threshold. As an example, the transmission power threshold may be defined as

Number

[0040] As described above, the total transmission power must be controlled to be less than the transmission power threshold. If it is determined that the total transmission power exceeds the transmission power threshold during a transmission opportunity, the terminal device 110 allocates power to the plurality of UL transmissions based on the priority associated with the first set of simultaneous transmissions (215). In the context of the present disclosure, a transmission opportunity may include several consecutive symbols within one slot or across a plurality of slots.

[0041] In some exemplary embodiments, the priority can indicate the priority in terms of transmission power allocation and / or transmission power reduction.

[0042] The terminal device 110 transmits at least a part 220 of the plurality of UL transmissions to the network device 120. The transmission power of the plurality of UL transmissions is allocated based on the respective power allocation priorities such that the total transmission power of at least a part of the plurality of UL transmissions is below the transmission power threshold.

[0043] The transmission power can be allocated in descending order of the power priority of each of the plurality of UL transmissions until the total transmission power reaches the transmission power threshold. Thus, in some embodiments, when the total transmission power reaches the transmission power threshold, the terminal device 110 can stop the remaining portions of the plurality of UL transmissions allocated with no transmission power. Further, or alternatively, in some embodiments, some of the plurality of UL transmissions may be allocated with a reduced transmission power.

[0044] In some embodiments, each power priority can be determined based on the priority index of the plurality of UL transmissions. For the purpose of determining the priority order of transmission power allocation, in some embodiments, a simultaneous PUCCH or PUSCH transmission having a higher priority index is defined to have a priority that is at least one level higher than that of a PUCCH or PUSCH transmission associated with the same, higher priority index. Further, or alternatively, in some embodiments, a simultaneous PUCCH or PUSCH transmission having a higher priority index may have a priority that is at least one level lower than that of a PRACH transmission in the primary cell.

[0045] In the example shown in FIG. 3, if the first set of simultaneous transmissions (310 and 320) and the third transmission 330 are associated with the same priority index, the terminal device 110 can allocate a higher power allocation priority to the first set of simultaneous transmissions (310 and 320) than to the third transmission 330. Further, or alternatively, the first set of simultaneous transmissions (310 and 320) can be allocated a lower power allocation priority than the PRACH transmission in the primary cell of the terminal device 110.

[0046] In the case of CA, the terminal device 110 can prioritize power allocation for UL transmissions in a cell involving simultaneous UL transmissions, including but not limited to simultaneous PUCCH, PUSCH, PRACH, or SRS transmissions. In other words, in the example shown in FIG. 3, the cell 102 involving simultaneous UL transmissions (310 and 320) is considered to have a higher priority than the cell 104 without simultaneous UL transmissions.

[0047] In some embodiments, in the case of the example shown in FIG. 3, the network device 120 manages the primary cell (i.e., cell 102) and a third transmission 330 on a secondary cell without simultaneous transmissions, i.e., cell 104. When the set of the first simultaneous transmissions (310 and 320) and the third transmission 330 are allocated with the same power allocation priority, the terminal device 110 can prioritize the transmission power allocation of the set of the first simultaneous transmissions (310 and 320) over the third transmission 330. The set of the first simultaneous transmissions (310 and 320) may include at least one of simultaneous PUCCH transmission, simultaneous PUSCH transmission, simultaneous PRACH transmission, or SRS transmission.

[0048] If the simultaneous PUCCH transmission or PUSCH transmission is not associated with a higher priority index, the simultaneous PUCCH transmission or PUSCH transmission can be allocated with a higher power allocation priority than any PUCCH transmission or PUSCH transmission having the same priority index. As shown in FIG. 3, in some embodiments where the set of the first simultaneous transmissions (310 and 320) and the third transmission 330 are associated with the same priority index, the terminal device 110 can allocate a higher power allocation priority to the set of the first simultaneous transmissions (310 and 320) than the third transmission 330.

[0049] For the simultaneous transmission of PUCCH or PUSCH with the same priority index, different levels of power allocation priority can be assigned, for example, considering the content or application of PUCCH / PUSCH, such as an aspect related to hybrid automatic repeat request (HARQ), scheduling request (SR), link recovery request (LRR), channel state information (CSI), etc.

[0050] In the case of scenario 400 as shown in FIG. 4, multiple UL transmissions of the terminal device 110 include a first set of simultaneous transmissions (410 and 420) in cell 102 and a second set of simultaneous transmissions (440 and 450) in cell 104. When the first set of simultaneous transmissions (410 and 420) and the second set of simultaneous transmissions (440 and 450) are associated with the same priority index, the terminal device 110 can determine the respective power allocation priorities based on the content of the first set of simultaneous transmissions and the second set of simultaneous transmissions.

[0051] In some exemplary embodiments, the levels of power allocation priority can be assigned in the following descending order, i.e., with the higher priority listed first. · PUCCH simultaneous transmission accompanied by at least one of hybrid automatic repeat request acknowledgement (HARQ-ACK) information, scheduling request (SR), link recovery request (LRR), or PUSCH simultaneous transmission accompanied by HARQ-ACK information · PUCCH simultaneous transmission by CSI, or PUSCH simultaneous transmission by CSI · Simultaneous transmission of PUSCH without HARQ-ACK information or CSI, or simultaneous transmission of PUSCH in the primary cell (e.g., in the case of a Type-2 random access procedure).

[0052] For simultaneous UL transmission within a single cell, the terminal device 110 may be configured (e.g., via RRC) for power allocation / reduction prioritization, or may be instructed (e.g., using existing or new fields / bits within DCI and / or MAC CE), or may be specified.

[0053] In scenario 300 as shown in Figure 3, cell 102 is composed of a first resource set and a second resource set, and the terminal device 110 may prioritize the transmission power allocation of one of the first transmission 310 and the second transmission 320 corresponding to the first resource set over the other transmission power allocation of the first transmission 310 and the second transmission 320 corresponding to the second resource set. The index of the first resource set may be higher or lower than the index of the second resource set, and whether to prioritize the UL transmission associated with the higher resource set index or the lower resource set index may be predefined or specified. Alternatively, the terminal device 110 may prioritize the UL transmission associated with a predetermined resource set index, and the indication indicating the predetermined resource set index may be received via at least one of an RRC message, a MAC CE, or a DCI.

[0054] When the first resource set and the second resource set are CORESETs, the terminal device 110 can prioritize the UL transmission corresponding to a predetermined CORESETPoolIndex. Additionally, or alternatively, in some exemplary embodiments, the terminal device 110 may prioritize the UL transmission corresponding to a relatively low CORESETPoolIndex, or alternatively, may prioritize the UL transmission corresponding to a relatively high CORESETPoolIndex.

[0055] When the first resource set and the second resource set may be SRS resource sets, the terminal device 110 may prioritize UL transmissions corresponding to a predetermined SRS resource set. Further, or alternatively, in some exemplary embodiments, the terminal device 110 may prioritize UL transmissions corresponding to an SRS resource set with a relatively high index or, alternatively, a relatively low index.

[0056] Alternatively, in some embodiments, the terminal device 110 may prioritize UL transmissions corresponding to a given closed loop (or at least one closed loop parameter) or, alternatively, a given open loop index (or at least one open loop parameter) for power control. In some cases, the predetermined closed loop index or the predetermined open loop index (or at least one corresponding parameter) that prioritizes the corresponding UL transmission may be indicated via DCI or MAC CE or may be configured for the terminal device 110 (e.g., via RRC).

[0057] In the case of scenario 300 as shown in FIG. 3, in some exemplary embodiments, the terminal device 110 prioritizes the transmission power allocation of one of the first and second transmissions 310 and 320 associated with the first cell identifier (e.g., physical cell identifier (PCI)) over the transmission power allocation of the other of the first and second transmissions associated with the second cell identifier (e.g., PCI), and the first cell identifier is higher or lower than the second cell identifier. In this case, whether to prioritize UL transmissions with a higher PCI or UL transmissions with a lower PCI may be predefined or specified. In some cases, the terminal device 110 may prioritize UL transmissions associated with a predetermined PCI (e.g., provided by a physical cell identifier or ID), and the indication indicating the predetermined PCI may be received via at least one of an RRC message, MAC CE, or DCI.

[0058] In some exemplary embodiments, the terminal device 110 may prioritize the transmission power allocation of one of the first transmission 310 and the second transmission 320 over the other based on the configuration locally stored in the terminal device. Alternatively, in some other embodiments, the terminal device 110 may prioritize the transmission power allocation of one of the first transmission 310 and the second transmission 320 over the other based on an instruction from the network device 120. This instruction may be carried, for example, in an existing field / bit in DCI or MAC CE, or a reserved field / bit, or a new field / bit.

[0059] In some exemplary embodiments, the terminal device 110 may prioritize the transmission power allocation of one of the first transmission 310 and the second transmission 320 associated with the first set of capability values over the other transmission power allocation associated with the second set of capability values. The first set of capability values may be higher or lower than the second set of capability values.

[0060] In some exemplary embodiments, the transmission power allocation for one of the first transmission 310 and the second transmission 320 is prioritized over the other based on the panel index or UL beam indication. In the above case, the terminal device 110 can prioritize UL transmissions related to a predetermined set of capability values (or panel), or a relatively low or high set of capability value indices (or panel indices).

In this case, the terminal device 110 can prioritize the UL transmission corresponding to the link or TRP or panel with a larger path loss.

[0065] For scenario 400, in an embodiment where the first cell 102 is the primary cell and the cell 104 is the secondary cell, the terminal device 110 assigns a higher power allocation priority to the set of first simultaneous transmissions (410 and 420) for the primary cell than to the set of second simultaneous transmissions (440 and 450) for the secondary cell.

[0066] Furthermore, in some embodiments, cell 102 is composed of a first resource set and a second resource set, and cell 104 is composed of a third resource set and a fourth resource set.

The first transmission 410 corresponds to the first resource set, the second transmission 420 corresponds to the second resource set, the fourth transmission 440 corresponds to the third resource set, and the fifth transmission 450 corresponds to the fourth resource set. In this case, for the primary cell, the terminal device 110 can prioritize the transmission power allocation of the first transmission 410 corresponding to the first resource set over the second transmission 420 corresponding to the second resource set. For the secondary cell, the terminal device 110 can prioritize the transmission power allocation for the fifth transmission 450 corresponding to the fourth resource set over the fourth transmission 440 corresponding to the third resource set.

[0067] In the case of single DCI operation, the first, second, third, and fourth resource sets may be SRS resource sets. In the case of multi-DCI operation, the first, second, third, and fourth resource sets may be CORESETs each identified by a CORESETPoolIndex.

[0068] In the case of inter-cell operation in scenario 400, UL transmission corresponding to a predetermined PCI may be prioritized, and there may be a PCI provided in the physical cell identifier and other PCIs (for so-called non-serving cells).

[0069] In some embodiments where a first set of simultaneous transmissions (410 and 420) and a second set of simultaneous transmissions (440 and 450) are associated with the same priority index, the terminal device 110 can determine respective power allocation priorities based on the content of the first set of simultaneous transmissions (410 and 420) and the second set of simultaneous transmissions (440 and 450).

[0070] According to exemplary embodiments of the present disclosure, a power control scheme is provided for simultaneous UL transmissions between cells and / or within a single cell. In particular, the power control scheme enables prioritization for transmission power allocation and / or reduction to prioritize / protect more important UL transmissions, mainly considering simultaneous UL transmissions within a cell. Accordingly, the performance of the UL transmission operation is improved.
